Clone from GitHub:
cd /tmp
git clone https://github.com/crouchingtigerhiddenadam/nano-hat-oled-armbian
Run the code (optional):
cd /tmp/nano-hat-oled-armbian
python3 oled-start3.py
Use ctrl+c to terminate.
Make the program directory:
sudo mkdir /usr/share/nanohatoled
Copy the program files:
sudo mv /tmp/nano-hat-oled-armbian/oled-start3.py /usr/share/nanohatoled/
sudo cp /tmp/nano-hat-oled-armbian/splash.png /usr/share/nanohatoled/
Copy service file:
sudo mv nanohatoled.service /etc/systemd/system
sudo systemctl daemon-reload
sudo systemctl enable nanohatoled.service
Reboot the system for the changes to take effect.
sudo reboot now
Get the latest code:
cd /tmp
git clone https://github.com/crouchingtigerhiddenadam/nano-hat-oled-armbian
Compile the code:
cd /tmp/nano-hat-oled-armbian
python3 -O -m py_compile oled-start3.py
Remove files from the previous version:
sudo rm /usr/share/nanohatoled/* -r
Copy the lastest version into place:
sudo mv /tmp/nano-hat-oled-armbian/oled-start3.py /usr/share/nanohatoled/
sudo mv /tmp/nano-hat-oled-armbian/splash.png /usr/share/nanohatoled/
Edit rc.local:
sudo nano /etc/rc.local
Then find the line:
exit 0
If required, change cd /usr/share/nanohatoled & /usr/bin/nice /usr/bin/python -n 10 oled-start.pyo & before exit 0 so the lines look like this:
cd /usr/share/nanohatoled && /usr/bin/nice -n 10 /usr/bin/python3 oled-start3.py &
exit 0
Save these changes by pressing ctrl+x, ctrl+y and enter as prompted at the bottom of the screen.
Compile the code:
cd /tmp/nano-hat-oled-armbian
python3 -O -m py_compile oled-start3.py
Reboot the system for the changes to take effect.
sudo reboot now
This does not require the FriendlyARM BakeBit or NanoHatOLED software to be installed. If this has already been installed you will need disable it.
sudo nano /etc/rc.local
Then find the lines:
/usr/local/bin/oled-start
exit 0
And comment out the oled-start line by adding # at the start of the line, so the lines look like this:
# /usr/local/bin/oled-start
exit 0
Save these changes by pressing ctrl+x, ctrl+y and enter as prompted at the bottom of the screen.
Reboot the system for the changes to take effect.
sudo reboot now
sudo nano /boot/armbianEnv.txt
Add i2c0 to the overlays= line, for example if the line appears as follows:
overlays=usbhost1 usbhost2
Then add i2c0 with a space seperating it from the other values:
overlays=i2c0 usbhost1 usbhost2
Save these changes by pressing ctrl+x, ctrl+y and enter as prompted at the bottom of the screen.
Reboot the system for the changes to take effect:
sudo reboot now
Enable the i2c0 either using armbian-config or changing /boot/armbianEnv.txt and reboot.
After reboot, run the following command:
sudo wget -O - \
https://raw.githubusercontent.com/crouchingtigerhiddenadam/nano-hat-oled-armbian/primary/install3.sh | \
sudo bash -
The command can be used to make a fresh installation or update an existing installation to the latest version.
Reboot the system for the changes to take effect:
sudo reboot now
